How can I assign more than one guild leader?

Question

Guys I have seen some guilds have more than one leader, I'm actually a leader in one but I do not see the option to assign another member to this rank.

Answer 1

You can only have one leader in a guild, the reason why you see some guilds that may look like they have multiple leaders is because you can name leader ranks and vice leader ranks the same, then they will be displayed as one rank only, even though they are seperated.

So to sum it up: If the leader rank and vice leader rank share the same name, it only displays itself as one rank, although they are separated.

Answer 2

All Tibia guilds have a basic structure. Even though guilds can have a complex hierarchy with up to 20 different individual ranks and countless individual titles, Tibia guilds are always made up of three basic ranks: guild leaders, vice leaders and regular members.
The rank of the guild leader is always the highest rank in a guild and this position must always be held by exactly one character. Characters who found new guilds will automatically be elevated to this rank, so guilds are usually led by their founders.

Short answer: You cannot have more than 1 leader in the guild.
